Google’s internal benchmarks of its own TPU, or tensor processing unit indicated that its purpose built AI board cleaned Nvidia’s clock when it came to number crunching and power consumption.
However this week Nvidia has blogged that Google’s numbers fail to take into account how wonderful its new boards are.
Google compaired its board to the older, Kepler-based, dual-GPU K80 rather than the Pascal based GPUs.
Nvidia moaned that Google’s team released technical information about the benefits of TPUs this past week but did not compare the TPU to the current generation Pascal-based P40.
While the TPU has 13x the performance of K80 is provisionally true, but there’s a snag. That 13x figure is the geometric mean of all the various workloads combined.
Nvidia’s argument is that Pascal has a much higher memory bandwidth and far more resources for inference performance than K80. As a result, the P40 offers 26x more inference performance than one die of a K80.
As Extreme Tech points out there are all sorts of things which are “unclear” about Nivida’s claims.
For example it is unclear if Nvidia’s claim takes Google’s tight latency caps into account. At the small batch sizes Google requires for its 8ms latency threshold, K80 utilization is just 37 percent of maximum theoretical performance. The vagueness of the claims make it difficult to evaluate them for accuracy.
Google’s enormous lead in incremental performance per watt will be difficult to overcome. Google said that its boffins modelled the expected performance improvement of a TPU with GDDR5 instead of DDR3, with more memory bandwidth.
Scaling memory bandwidth up by 4x would improve overall performance by 3x, at the cost of ~10% more die space. So, it is saying that it can boost the TPU side of the equation as well.
While no one is saying that the P40 is slower than the K80, but Google’s data shows a huge advantage for TPU performance-per-watt compared with GPUs, particularly once host server power is subtracted from the equation.
Basically GPU has lots of hardware that a chip like Google’s TPU simply doesn’t need.
Microsoft is touting operating system-wide power efficiencies in a recent preview of Windows 10, claiming that the technology will reduce notebook battery consumption by 11% on laptops equipped with the newest processors.
The technology, temporarily tagged as “Power Throttling,” was enabled on all copies of Windows 10 Insider build 16176, which Microsoft released Friday. Insider is the beta program Microsoft runs for both enthusiasts and businesses. The latter rely on Insider to learn how the OS will change for the next feature upgrade, as well as for testing the upgrade prior to deploying the final code when it is shipped several months later.
“With ‘Power Throttling,’ when background work is running, Windows places the CPU in its most energy efficient operating modes — work gets done, but the minimal possible battery is spent on that work,” Bill Karagounis, director of program management for Insider, said in a post to a company blog.
The CPU throttling is triggered on an app-specific basis by a detection system Microsoft integrated with the OS, said Karagounis. Like other such technologies, Microsoft’s is meant to recognize foreground tasks — such as active apps — as well as persistent applications, like music streaming applications, then give them full access to the processor. Other apps, or even individual processes within an app, that are classified as “background,” are restricted in how they impact the CPU’s power usage. For instance, they may not be allowed to kick the processor into its higher-frequency, higher-power, higher-consumption mode.
Power Throttling works only on Intel processors with that firm’s Speed Shift, a feature of sixth-generation and later CPUs, including “Skylake” and the newer “Kaby Lake.”
Recognizing that most personal computers are laptops and that battery longevity is a major factor in productivity, Microsoft has aggressively promoted Windows 10’s power savings, notably in the boosterism behind Edge, the OS’s default browser.
The Redmond, Wash. company isn’t working in a vacuum: Other operating systems also try to eke out more battery life by scaling back CPU use. Apple’s iOS, for instance, switches to a low-power mode when an iPhone or iPad battery reaches about 20% capacity. Among other things, the iOS mode halts background app refreshing and stops automatic email fetching.
Microsoft first added Power Throttling to Windows 10 in January, saying that it had turned it on for a subset of Insider-equipped devices as an experiment and promising to provide an update in mid-February. That update never appeared, hinting that Microsoft pulled it from inclusion in the then-upcoming Creators Update, the feature upgrade released April 11.
The first opportunity most users will have to apply Power Throttling will be with 2017’s second feature upgrade. Microsoft has not revealed a release timetable, but most experts expect it to appear this fall.
Facebook Inc has provided a peek inside a secretive unit headed by a former chief of the Pentagon’s research arm, disclosing that the social media company is studying ways for people to communicate by thought and touch.
Facebook launched the research shop, called Building 8, last year to conduct long-term work that might lead to hardware products. In charge of the unit is Regina Dugan, who led a similar group at Alphabet Inc’s Google and was previously director of the U.S. Defense Department’s Defense Advanced Research Projects Agency, or DARPA.
Dugan told software developers at Facebook’s annual F8 conference that the company was modeling Building 8 after DARPA, a government office founded in the 1950s that gave the world the internet and the miniaturized GPS receivers used in consumer devices.
Any hardware rollouts are years away, Dugan said in a speech. Potential products could, if successful, be a way for Facebook to diversify beyond its heavy reliance on advertising revenue.
One example of Building 8’s work so far, Dugan said, was an attempt to improve technology that allows people to type words using their minds.
“It sounds impossible, but it’s closer than you may realize,” Dugan said.
Using brain implants, people can already type eight words a minute, she said. Facebook’s goal, working with researchers at several U.S. universities, is to make the system non-invasive, as well as fast enough so that people can type 100 words a minute just by thinking.
Possible uses include helping disabled people and “the ability to text your friend without taking out your phone,” she said.
Another Building 8 project, she said, was trying to advance the ability to communicate through touch only, an idea with roots in Braille, a writing system for the blind and visually impaired.
A video played at the conference showed two Facebook employees talking to each other through touch. As one employee, Frances, wore an electronic device on her arm, the other, Freddy, used a computer program to send pressure changes to her arm.
“If you ask Frances what she feels,” Dugan said, “she’ll tell you that she has learned to feel the acoustic shape of a word on her arm.”
In December, Facebook signed a deal with 17 universities including Harvard and Princeton to allow swifter collaboration on projects with Dugan’s team.
Bose Corp spies on its wireless headphone owners by using an app that tracks the music, podcasts and other audio they listen to, and violates their privacy rights by selling such data without permission, a lawsuit charged.
The complaint filed by Kyle Zak in federal court in Chicago seeks an injunction to stop Bose’s “wholesale disregard” for the privacy of customers who download its free Bose Connect app from Apple Inc or Google Play stores to their smartphones.
“People should be uncomfortable with it,” Christopher Dore, a lawyer representing Zak, said in an interview. “People put headphones on their head because they think it’s private, but they can be giving out information they don’t want to share.”
Bose did not respond on Wednesday to requests for comment on the proposed class action case. The Framingham, Massachusetts-based company has said annual sales top $3.5 billion.
Zak’s lawsuit was the latest to accuse companies of trying to boost profit by quietly amassing customer information, and then selling it or using it to solicit more business.
After paying $350 for his QuietComfort 35 headphones, Zak said he took Bose’s suggestion to “get the most out of your headphones” by downloading its app, and providing his name, email address and headphone serial number in the process.
But the Illinois resident said he was surprised to learn that Bose sent “all available media information” from his smartphone to third parties such as Segment.io, whose website promises to collect customer data and “send it anywhere.”
Audio choices offer “an incredible amount of insight” into customers’ personalities, behavior, politics and religious views, citing as an example that a person who listens to Muslim prayers might “very likely” be a Muslim, the complaint said.
“Defendants’ conduct demonstrates a wholesale disregard for consumer privacy rights,” the complaint said.
Zak is seeking millions of dollars of damages for buyers of headphones and speakers, including QuietComfort 35, QuietControl 30, SoundLink Around-Ear Wireless Headphones II, SoundLink Color II, SoundSport Wireless and SoundSport Pulse Wireless.
He also wants a halt to the data collection, which he said violates the federal Wiretap Act and Illinois laws against eavesdropping and consumer fraud.
Dore, a partner at Edelson PC, said customers do not see the Bose app’s user service and privacy agreements when signing up, and the privacy agreement says nothing about data collection.
Edelson specializes in suing technology companies over alleged privacy violations.
NAND flash prices have been inflating excessively lately and Phison Electronics chairman Khein Seng Pua warned that prices are set to go up again in the third quarter as end-market demand surges.
He told Digitimes that while prices might decrease a little in the second quarter, Chipmakers’ ongoing transition from 2D to 3D NAND memory has led to tight supply and inflated the chip prices.
System OEMs are reluctant to deliver their products as the more they sell the more they lose due to soaring NAND flash costs, Pua warned.
Meanwhile, chipmakers’ supply to channel distributors has been falling short of demand prompting the distributors to promote lower-capacity storage devices.
“Channel distributors particularly those in China have turned to promote 96GB SSDs instead of 128GB ones due to insufficient chip supply,” Pua said.
Distributors have even experienced tight supply of 8GB and 4GB eMMC devices.
Pua believes NAND flash prices will soon see correction following excessive gains but Apple’s new iPhone will take a lot of NAND flash from the market and push prices up again.
Chipmakers’ transition to 3D NAND memory will become smooth in general between May and June, which will help ease the supply shortages, Pua indicated.
The industry’s output of 64-layer 3D NAND will account for more than half of the total output in the fourth quarter of 2017 Pua said.
Last year, the average “levelized cost” or total cost of generating power from solar worldwide dropped 17% percent, onshore wind costs dropped 18% and offshore wind turbine power costs fell 28%, according to a new report from the United Nations and Bloomberg New Energy Finance (BNEF).
“Well, after the dramatic cost reductions of the past few years, unsubsidized wind and solar can provide the lowest cost new electrical power in an increasing number of countries, even in the developing world — sometimes by a factor of two,” Michael Liebreich, chairman of the Advisory Board at BNEF, said in the report.
The average capital cost for solar power projects of new construction in 2016 was 13% lower than in 2015, while for onshore wind the drop was 11.5% and for offshore wind, 10%.
“It’s a whole new world: even though investment is down, annual installations are still up; instead of having to subsidize renewables, now authorities may have to subsidize natural gas plants to help them provide grid reliability,” Liebreich said.
Last year, more gigawatts of solar power were added (75GW) than of any other technology for the first time. Trailing behind solar, in order of net gigawatts installed, were wind, coal, gas, large hydroelectric, nuclear and biomass.
Renewable energy accounted for 55% of new worldwide power last year, or a total of 138.5 gigawatts (GW). That compares with 127.5GW of new renewable energy in 2015; and renewable power installed in 2016 was done so at a cost 23% lower than 2015, the report showed.
Since 2010, the dollars committed per year to new renewable energy worldwide — excluding hydroelectric — have increased roughly five-fold, and have since oscillated between $234 billion and $312 billion, the report said.
“A major reason why installations increased, even though dollars invested fell, was a sharp reduction in capital costs for solar photovoltaics, onshore and offshore wind,” the report said.
At the same time, because of the drop in prices, last year, the overall investment in renewable energy plummeted 23% to $241.6 billion from the record established in 2015; it was the lowest total investment since 2013.
Investment in new renewables capacity was roughly double that in fossil fuel generation in 2016, for the fifth successive year. The proportion of global electricity coming from renewable sources rose from 10.3% in 2015 to 11.3% in 2016, and prevented the emission of an estimated 1.7 gigatons of CO2.
Smart energy hardware such as smart meters, energy storage sources and associated IoT technologies also saw record investments last year. Asset finance for smart meters and energy storage, plus equity raised for specialist companies in energy efficiency, storage and electric vehicles, totalled a record $41.6 billion last year. That was up 29%.
In the U.S., utilities and private energy companies are increasingly investing in smart grid technology, including microgrids.
Facebook Inc is wants to capitalize off of the technology known as augmented reality, a mix of the real and digital worlds best known from the hit smartphone game Pokemon Go, Chief Executive Mark Zuckerberg said.
Speaking at F8, the company’s annual conference for software developers, Zuckerberg said Facebook was an obvious hub for businesses to reach people and experiment with augmented reality, although he did not suggest the company was planning to make similar games itself.
Pokemon Go, jointly developed by Nintendo Co and Niantic Inc, has generated masses of followers around the world as players use their phones to capture animated characters that appear in real locations.
Other uses of augmented reality have included the ability to hang out with a hologram of “Mad Men” star Jon Hamm or assemble a virtual human brain, all on mobile devices.
A recent push by Facebook to add camera features to its suite of smartphone apps will help the company popularize similar features, Zuckerberg said.
“Even if we were a little slow to add cameras to all our apps, I’m confident that now we’re going to push this augmented reality platform forward,” he said.
For a company that began as a way for college students to see pictures of each other, Facebook’s move toward augmented reality represents another step in its long evolution. It also raises the stakes for its competition with rival Snap Inc, the maker of Snapchat that describes itself as a camera company.
Zuckerberg said people could use the technology to leave a virtual note for a friend at a bar, or to find virtual street art on a wall that in real life is blank.
“This isn’t just about finding a Pokemon in a one-block radius,” he said.
Eventually, he said, people would use augmented reality on eyewear, although he did not give any details about possible Facebook hardware.
In 2014, Facebook acquired its Oculus virtual reality goggles unit for $2 billion, although that division is a long way from making a mass-market product or contributing significantly to the company’s earnings.
As part of his conference address, Zuckerberg addressed shortcomings on another major project, Facebook’s push into video. He said the service needed to do more to prevent the spread of violent videos, such as one on Sunday of a fatal shooting in Cleveland that was visible on the site for two hours.
Baidu Inc has announced plans to launch its self-driving car technology for restricted environment in July before gradually introducing fully autonomous driving capabilities on highways and open city roads by 2020.
The project is named Apollo after the lunar landing program, the Chinese search giant said, adding it would work with partners who provide vehicles, sensors and other components for the new technology.
As part of its push into artificial intelligence (AI), the company in January named former Microsoft Corp executive Qi Lu as chief operating officer.
Two months after the appointment, Baidu’s chief scientist Andrew Ng, who led AI and augmented reality (AR) projects, said he would step down.
The company also launched a $200 million fund in October to focus on AI, AR and deep learning, followed by a $3 billion fund announced in September to target mid- and late- stage start-ups.
“AI has great potential to drive social development, and one of AI’s biggest opportunities is intelligent vehicles,” Qi said in a statement.
In November, Baidu and German automaker BMW AG said they would end their joint research on self-driving cars due to differences in opinion on how to proceed.
Technology and automotive leaders contend that cars of the future will be capable of completely driving themselves, revolutionizing the transportation industry, with virtually all carmakers as well as companies such as Alphabet’s Google and parts supplier Delphi investing heavily in developing the technology.
You might seen we’ve writing about millimeter waves several times. and we usually attributed this term to 5G. AMD has just acquired Nitero, a millimeter wave company that wants to use this technology to cut the cord on your VR and AR headset.
AMD has figured out that cables are a very limiting factor in a Virtual Reality or Augmented Reality. This is not a big secret as even if you only had a few minutes to play with one, you quickly realize that making things wireless is more comfortable.
The acquisition provides AMD with a broader portfolio of IP capable of enabling VR headset and solution providers with key technology required to create more immersive computing experiences.
Mark Papermaster, AMD chief technology officer and senior vice president said:
“Unwieldly headset cables remain a significant barrier to drive widespread adoption of VR. Our newly acquired wireless VR technology is focused on solving this challenge, and is another example of AMD making long-term technology investments to develop high-performance computing and graphics technologies that can create more immersive computing experiences.”
Nitero has designed a phased-array beamforming millimeter wave chip to address the challenges facing wireless VR and AR. This is the same frequency that Intel and Qualcomm will use for Wi-Gig. This enables very fast speeds within a room, but due to its high frequency the signal won’t really penetrate any walls.
This is not that important for the VR and AR markets as we don’t see a case where you need to leave an office or a room with the VR / AR headset on.
The 60GHz technology has the potential to enable multi-gigabit transmit performance with low latency in room-scale VR environments. It will rely heavily on the beamforming characteristics to solve the requirement for line-of-sight associated with traditional high-frequency mm-wave systems. The main goal is potentially eliminating wired VR headsets and letting users to become more easily immersed in virtual and augmented worlds.
Nitero co-founder and CEO Pat Kelly said:
“Our world class engineering team has been focused on solving the difficult problem of building wireless VR technologies that can be integrated into next-generation headsets. We are excited to play a role in furthering AMD’s long-term technology vision.”
Pat joined AMD as corporate vice president, Wireless IP highlighting the importance of the whole acquisition and the whole technology potential. Fudzilla calls this a step in the right direction.
Ride-services company Uber Technologies Inc may be forced to provide riders a way to tip their drivers, despite its longstanding resistance, if a plan by New York City’s taxi regulator is implemented.
The New York City Taxi and Limousine Commission has announced intentions to propose a rule no later than July that would require all for-hire vehicles to allow passengers to tip drivers using the same method they use to pay for the ride. In Uber’s case, this would involve adding a tipping feature within the its smartphone app.
The commission said its proposal is a response to driver concerns over falling wages, as Uber has reduced fares in New York City and across the country. Tips could help boost drivers’ income.
Uber has said previously it opposed tipping because it was an inconvenience to passengers and slowed the transaction between rider and driver.
“I found myself having to work longer hours away from my family to earn the same money,” Luiny Tavares, who has driven for Uber for five years, said on a call with reporters that was organized by the Independent Drivers Guild.
The guild, set up last year to advocate for drivers, started a campaign last summer to pressure Uber to add a tipping feature in its app. Uber was “unable to move on the option,” said guild founder Jim Conigliaro, so the guild brought the issue to the taxi commission.
Any tipping proposal faces a protracted process before it becomes a rule Uber must follow. The taxi commission has the authority to initiate rulemaking on its own, but rules must be certified by city legal authorities. There is also 30-day public comment period and public hearing, and a board of commissioners votes on the final rule.
“We have not seen the proposal and look forward to reviewing it,” said Uber spokeswoman Alix Anfang. “Uber is always striving to offer the best earning opportunity for drivers and we are constantly working to improve the driver experience.”
Adding a tipping feature to Uber’s app would remove one significant difference between Uber and its chief U.S. competitor, Lyft. Lyft has a smaller market share but is the preferred service of many drivers because it allows tipping through the smartphone app. Lyft said in March that its drivers have earned more than $200 million in tips since the company’s founding.
Companies running Firefox, and testing the browser using the “Aurora” track, will be automatically migrated to the “Beta” channel today.
“It became clear that Aurora was not meeting our expectations as a first stabilization channel,” wrote Dave Camp, director of engineering for Firefox; Sylvestre Ledru, the browser’s release manager; and Ali Spivak, head of developer marketing, in a post to a Mozilla blog.
Mozilla has offered multiple versions of each Firefox edition since 2011, when it began offering four builds — Nightly, Aurora, Beta and Release — each of which was supposed to be more stable than the previous.
“We have more modern processes underlying our [release] train model, and believe we can deliver feature-rich, stable products without the additional 6-8-week Aurora phase,” said Camp, Ledru and Spivak.
In that “train” approach, Mozilla added a new feature to the least stable version, Developer, then when the feature was ready, moved it to the next track, Aurora. As development progressed, the feature would shift to Beta and then finally to Release.
But Mozilla acknowledged that the system had sometimes failed. “The release cycle time has required that we subvert the model regularly over the years by uplifting new features to meet market requirements,” the company admitted in an accompanying FAQ, referring to times when it has had to skip one of the tracks or shorten the time a feature spent on one.
Firefox users on the Aurora channel were to be moved to Beta today, according to the FAQ. Aurora will not be updated after tomorrow, when Firefox 53 is to ship in final, or Release, form.
With Aurora’s disappearance, Mozilla will rely on Beta for the first widespread distribution of each edition of Firefox. To make up for Aurora’s absence, each beta will be rolled out in stages, just as Release has long been, with the idea that if major problems crop up, they do so early on and thus affect only a subset of customers before the spigot is turned off.
Aurora’s elimination will not increase the frequency of Release builds issued or decrease the time between each Release version; the latter will continue to range from six to nine weeks. Nor will the already-slated dates for future versions of Firefox ESR (Extended Support Release) change. That edition, designed for enterprises and other large organizations, remains stable for approximately a year. Much like Windows 10’s LTSB (Long-term Servicing Branch), ESR receives only security updates.
Ditching Aurora, however, will let Mozilla move a new feature from inception to final about six to eight weeks faster than before.
IRobot, the maker of the popular Roomba robotic vacuum, has filed a slew of lawsuits alleging that its rivals including The Hoover Co and Black & Decker Corp have been using its patented technology without permission.
Bedford, Massachusetts-based iRobot filed lawsuits in federal court in Boston against Hoover, Black & Decker, Bobsweep Inc and Bissell Homecare Inc. IRobot said they infringe on several of its patents covering the idea of an autonomous floor-cleaning robot.
“iRobot will not stand by while others offer products that infringe on our intellectual property,” the company said in a statement.
Representatives for Hoover, Black & Decker, Bissell and Bobsweep did not immediately return a request for comment.
iRobot also sued China-based Shenzhen Silver Star Intelligent Technology Co, which iRobot said manufactures Hoover and Black & Decker vacuums.
One of the oldest and best-known makers of traditional vacuums, Hoover is now owned by TTI Floor Care North America, a subsidiary of Hong-Kong based Techtronic Industries Company Limited.
Black & Decker is a subsidiary of New Britain, Connecticut-based Stanley Black & Decker Inc.
IRobot created the market for robotic vacuums when it launched Roomba in 2002 but has faced increased competition from other appliance makers.
Hoover launched its line of Quest robotic vacuums, over which iRobot is suing, in 2016. Other vacuums at issue in the lawsuits are the Bissell SmartClean, Bobsweep’s Bobi and Black & Decker’s BDH5000WM.
Residential robotic vacuums generated $1.5 billion in global revenues in 2016, an amount expected to reach $2.5 billion by the end of 2021, according to the market research firm Future Market Insights. The overall market for household vacuums was $12 billion in 2015, according to Global Market Insights, another research firm.
AMD has released a new custom “balanced” power plan for those using Ryzen CPU on Windows 10 OS.
Until today, AMD Ryzen CPU users were limited to using the “high performance” plan in Windows 10 OS, at least if they want to get most performance out of their Ryzen CPU. Now, AMD has released a new tweaked “balanced” power plan that should provide a compromise between performance and power efficiency which “automatically balances performance with energy consumption on capable hardware”.
According to the explanation posted by AMD’s Robert Hallock, the new power plan reduces the times and thresholds for P-state transition in order to improve clockspeed ramping as well as disables core parking for “more wakeful cores”.
These tweaks are apparently enough for the new plan to provide similar performance to the Microsoft’s “high performance” power plan setting, at least according to AMD’s own slides. As far as power is concerned, the new balanced power plan does not change how the processor handles low-power idle states, so basically, you’ll get additional performance without compromising the power efficiency.
The new balanced plan is quite simple to install and you can find both the download link as well as check out further explanation over at AMD’s community blog. AMD will also include the final power plan with next AMD chipset drivers for Ryzen CPUs.
The myth that Macs are somehow more secure than other operating systems appears to be a myth according to a Threat Report by McAfee Labs.
Attacks on Macs have risen by 744 percent in 2016 and there are more than 460,000 malware samples on Mac machines found. Although this is not a particularly high number you have to acknowledge that this is one security company and on a single machine.
It appears that after years of leaving Macs alone, virus writers are suddenly taking an interest in knocking them over and the security by obscurity measures, along with faith-based defences are not working.
The Tame Apple Press has rushed to say that “despite the dramatic increase in macOS malware attacks, Mac owners need not be too alarmed”.
One newspaper even said that the attacks were just irritating and not like the “true malware attacks” that Windows users have to suffer.
Most of the attacks were just adware which automatically generates and displays advertising material, including banners or pop-ups, whenever a user is online, the Tame Apple Press tried to reassure Apple fanboys.
Last summer, Mac owners were warned about a new malware dubbed Backdoor.MAC.Elanor – a nasty piece of code that infects the OS X operating system and gives hackers complete access to the files on the computer.
Two months ago, Microsoft had extended support for Windows 10 version 1507 — Microsoft labels feature upgrades by year and month — from March to May, but did not specify the date in the latter month.
The May 9 retirement was quietly announced on several support documents, including the “Windows lifecycle fact sheet,” which lists several kinds of deadlines for various versions of the operating system.
Another document put it plainly. “The time has now come to end servicing for version 1507,” the support document read.
Stopping support for Windows 10 editions — Microsoft released the fourth on Tuesday — is an important part of the company’s software-as-a-service model. The company has pledged to support an individual edition, such as 1507, not for 10 years, as policy required for, say, Windows 7 or 8.1, but only for 18 months or so. That mandate insured Microsoft would not need to craft security patches, fix other bugs or add new features for an increasing number of versions.
By the time Windows 10 1507 slips off the list, it will have been supported for about 21 months. Part of the reason it lasted longer than Microsoft’s stated norm was because the firm issued just one feature upgrade — v. 1607 — in 2016.
The next Windows 10 edition, v. 1511, could be purged from support as soon as early October. That’s because Microsoft has committed to simultaneously supporting just two Current Branch for Business (CBB) builds. At the release of N+2 onto CBB, the company starts a 60-day-or-so countdown. At the end of the 60 days, N drops off the support list. N+1 then becomes N and N+2 morphs into N+1.
Under that policy, N would be 1511, N+1 version 1607 (released in August 2016) and N+2 1703 (this month’s feature upgrade). Version 1703 will likely be promoted to the CBB in four months, or August; two months more would put 1511’s support demise in October.
Users running 1507 must have upgraded to 1511, 1607 or 1703 by May 10 to receive future security patches, and other fixes or enhancements. Windows 10 1507 will not suddenly fail to boot, however, or degrade, as do copies that have not been activated with a product key.
The only exceptions will be customers whose devices are running v. 1507 from the Long-term Servicing Branch (LTSB), a special release track available only to organizations using Windows 10 Enterprise.
